206 PITTONIA. 
tently assigned it a trivial name, T. montanum, which he 
afterwards found untenable as being homonymous; see Sp. 
Pl. pp. 770 and 772. 
4. C. BADIA. Trifolium badium, Schreb. in Sturm, l. c. 
(1804); Savi, Obs. 113 (1810). T. spadiceum in part of Linn. 
Fl Suec, but not as to the type. Melilotus lupulina, var. 
Lam. Fl. Fr. ii. 593 (1778). Amarenus badius, Presl, l. €. 
(1880). Evidently related to C. spadicea, and confounded 
with that species by Linneeus; but readily distinguished by 
its short and subglobose heads, and a banner far longer in 
proportion to the other petals. Its flowers change only to a 
chestnut color, not to a dark brown ; and its leaflets are all 
sessile. Linnæus probably did not know the plant, and he 
erroneously cited a classic figure of it—Barrelier, t. 1024— 
as representing his T. spadiceum. But it is agreed by all 
European students of these plants that Barrelier's figure 
represents the present species. Nor can it be successfully 
contended here, as in the case of C. agraria, that because of 
Linneus’ having cited this figure the name spadicea must 
be applied to this plant; for the Linnsan description, and 
even the name spadicea, are distinctly diagnostie of the 
northern plant of the elongated and dark-brown spikes. 
5. C. PRocUMBENS, Desv. Fl. Anjou, 338 (1827). Trifolium 
procumbeus, Linn. Sp. 772 (1753). Amarenus procumbens, 
Presl, 1. c. (1830). This appears to be the most common of 
the species which have established themselves in North 
America, and is the only one which has hitherto been ac- 
credited as naturalized on the Pacific coast. But C. agraria 
is certainly frequent in western Washington, and even forms 
a part of the “ T. procumbens” of Mr. Howell's Flora, as 
copious specimens sent me by him demonstrate. 
6. C. DUBIA. Trifolium dubium, Sibth. Fl. Oxon. 231 
(1794). Also naturalized on both slopes of our continent, 
according to Britton & Brown, Ill. Fl. 275.
